Abstract
High-volume blood flow restriction (BFR) training uses low loads prescribed as a percentage of 1-repetition maximum (1RM), yet performance during these protocols depends on muscular endurance, resulting in variable effort among participants. Measuring concentric velocity during BFR exercise may provide a practical way to monitor performance and effort. This study characterised velocity decline during low-load bench press with BFR, and assessed the reliability of repetition velocity during this exercise.
